Home Addition Cost in Toronto, What to Expect

by | Dec 12, 2023 | Home Additions

If you are thinking of home addition cost in Toronto, you may be wondering how much to budget. As a homeowner, budgeting for such an undertaking can seem like an overwhelming process, but it doesn’t have to be. In this blog post, we will break down the cost of a typical home addition project in Toronto. We will highlight some of the factors that affect the cost and give you a rough estimate of how much you can expect to spend.

Size of the Home Addition

The size of your home addition is one of the most significant factors that affect the overall cost. Generally, the larger the addition, the more expensive it will be. Homeowners in Toronto can expect to pay between $200 and $600 per square foot for a new addition. However, it is essential to keep in mind that the exact cost will depend on various factors, such as the type of construction materials used, the specific design of the addition, and the complexity of the project.

Type of Room

Another significant factor that affects the cost of an addition is the type of room you want to build. Some rooms are more expensive to construct than others. For instance, kitchens and bathrooms tend to be more expensive due to their unique features and the required plumbing. In contrast, bedrooms and living rooms tend to be less expensive because they do not require as many specialized features. Keep in mind that the more embellishments you add to your room, the higher your costs will be.

Building Codes

Home additions in Toronto must meet specific building codes and regulations (Check out City of Toronto, Home Addition Section), which can affect the overall cost. For instance, you may need to add specialized fire safety features, which can increase the cost of the project. It would be best to hire a professional contractor who understands the rules and regulations in Toronto to ensure that your addition meets the required standards.

Contractor Fees

The cost of the addition will also depend on the contractor you hire for the project. Different contractors have varying fees, and it is important to choose one that fits your budget. It is worth noting that choosing a contractor based solely on cost can be risky. Consider other factors such as their experience, their portfolio of completed projects, customer reviews, etc. It is always a good idea to compare multiple bids to get a better idea of your options.

Other factors

You’ve covered the major factors, but other things like site preparation, permits, utility enhancements, and other additional features can significantly impact your project’s cost, so it is important to factor them in as well. You can inquire about your project’s details and budget required with our senior project manager, simply check our Consultation Request Page.


In conclusion, home addition cost in Toronto can vary significantly, based on various factors we’ve highlighted. It’s always better to have a plan and research what you’re getting into before taking on a home addition project. Understanding the various factors beyond size and type of room can help you make an informed decision about your addition project, both in terms of budget and value.
